Cystoealstometer (Bladder Monitor Device)-Home Use

The investigators have developed a novel pressure monitoring device called a 'cystoelastometer' that connects to a drainage end ofastandard urinary catheters that are used by patients with a neurogenic bladder on daily clean intermittent catheterization. The device has already been demonstrated to be accurate in measuring bladder pressure compared to the gold standard urodynamics that are performed in the clinic or hospital. This study will assess the patients and care givers ability and experience using the cystoelastometer device in a home setting.

Inclusion Criteria: * Patients seen in the University of Iowa Pediatric Urology Clinic with neurogenic bladder managed with clean intermittent catheterization. * Patients who haven't had any change in management * Patients who had recently had UDS (urodynamic study) performed Exclusion Criteria: * phone which is not iOS compatible
